Tissue engineering is definitely an exciting field – the ability to create living biological tissue in a lab could allow scientists to do things such as testing new drugs without the need for human subjects, or even to create patient-specific replacement organs or other body parts.
While some previous efforts have yielded finished products that were very small, a microfluidic device being developed at the University of Toronto can reportedly produce sections of precisely-engineered tissue that measure within the centimeters.
